Over the past few years, astronomers have been able to figure out that pulsars are extremely important pieces of the cosmic puzzle. Studying these structures could reveal more about the existence of strong gravitational interactions, while at the same time confirming the Theory on General Relativity.
The theory, pro... |

One of the things that initiate the collapse of molecular hydrogen clouds into protostars is the fact that the massive structures exceed a critical density threshold. Astronomers call this limit the Jeans mass, and recently they discovered that some stars from outside the influence of this criterion.
There are ma... |

Establishing the density of a cell is something that scientists have been trying to do for many years, but thus far all efforts have failed. Enter a new device from researchers in the United States, that is capable of finally assessing the density of single cells. The basic principle experts used was discovered more ... |

How many of you have ever wondered about how a song played on, say, the Martian surface would actually sound? Assuming you pressed the "play" button on a Hi-Fi audio system, would Bach's famous “Toccata and Fugue in D Minor” sound the same as on Earth, as you would expect? Scientists say that no, it... |

The Galileo thermometer, or thermoscope, is a device named after the Italian physicist Galileo Galilei and designed to measure temperatures with a relatively good accuracy, although today it is mostly used as a decoration item. Unlike most classical thermometers, the Galileo thermoscope relies on the buoyancy princip... |

It's almost amazing how violins made by applying three century old technology cannot be matched in sound quality by violins made through modern technology. No wonder some of these musical instruments value several hundred million dollars each and made Stradivari and Guarneri del Gesu some of the most famous mast... |

Often called 'frozen smoke', aerogels represent materials derived from a gel compound in which the liquid components have been switched with a gas. Despite the fact that their names suggests that they are gel-like, aerogel materials are anything but that. They are dry materials and have properties similar t... |

Scientists performed a new study to evaluate what countries are most at risk of what they call "small" asteroid impact. The term small must not be taken literally, since a 1-kilometer-wide asteroid may not be large in astronomical terms, but it still can produce a disaster.Using a new computer software, called NEOim... |

Generally, the action of swarming applies to the animal kingdom, for instance to schools of fish, groups of insects and birds. This aggregation of similar elements that help animals find mates and survive predator attacks has now been successfully achieved in artificial systems made of copper rods.Vijay Narayan of t... |

The name comes from the fact that Brazil nuts, in a container of mixed nuts, always come on top when the container is shaken, even though they are the largest and heaviest in the bunch. This phenomenon also happens with other large-sized elements in a mix, like cereals in a muesli mix, but nobody has managed to pre... |
